On the whole, I think I have the measure of the start/stop and it seems to work fairly well...however, on occasion it seems overly keen to cut and does so before I have come to a complete stop - usually in slow moving traffic or at a junction where I am slowing right down and readying to stop.   It starts up fine as soon as I lift off the brake a touch, but it would be better if it was a bit less keen...   Is there any tuning/tweaking I or the dealer can do? Any one else have this issue?
